A T TOR/V Patented Oce 25, 1932 UNi'rED STATES-PATENT OFFICE STANLEY W. NICHOLSON, OF MILWAUKEE, WISCONSIN, ASSIGNOB TO BBIGGS &` STRAT- TON OOBPOBATION, F MILWAUKEE, WISCONSIN, A CORPORATION OF :DELAWAREA WINDOW REGULATOR Application illed October 28,

This invention relates to window regulators and more particularly to window regulators of the link t pe in which the window is raised and lowere through a series of levers and links.

It is an obect of the present invention to devise a win ow regulator which will raise and lower the window parallel lto itself so as to prevent binding between the window casin and the window.

t is a further object of the invention to provide means for readily attaching or dctaching a window from the window regulator.

Another object of the invention is to prolo vide a simple window regulator with a minimum number of moving parts which may be readily attached in place and which will effect positivel parallel movement of the pane, and

other obJects will become apparent as the description proceeds.

A structure embodying the invention is illustrated in the accompanying-drawings and will be hereinafter fully described, the invention residing in certain novel features which will be particularly pointed out in the apnded claims.

In the drawin Fi re 1 is an vational view of a window regu ator in place'in 1the door, parts of the 3o door being broken away to more clearly illustrate the` invention, the window being shown in lowered position;

vFigure 2 is a view similar to Fig. 1 showing the window regulator per se and with the window near its uppermost position;

Fi re 3 is a cross section on the line 3-3 of 1g. 1, looking in the direction of the arrows;

Fi re 4 is a cross section on the line 4-4 rof Fig. 1, looking in the direction of the ar- Fi re 5 is a cross section on the line 5--5 of Fig. 1, looking in the direction of the arrows; and i Figure .6 is'a rear view showing the selgment gear and the pinion for operating t e regulator.

Referring to the accompanying drawings in which like numerals indicate like parts 50 throughout the several views, the door or issi. semi no. 571,516.

other panel o10 of the car is rovided with a pair of parallel walls 12 an 13, the walls 13 being assumed to be the outer wall of the car.

A window casing 15 having a sill 16v is provided in the car and mounts a window 17 therein, themounting member for the window comprising a resilient cushion 18 mounted in a channel 20. The window is adapted to move. from a lower position in which the window is below the sill 16 to an upper position in which the window contacts the upper edge of the casinv 15; the movement bein(T eiected by a regulator, generally designate 25, and more particularly described as follows:

The regulator 25 is mounted on the wall 12 which forms a base for the regulator through a pair of brackets, generally designated 28 and'29, the operating members of the regulator comprising a pair of arms 31 and 33 pivotally mounted to the brackets 28 and 29 respectively and connected together b a link 35 which is` ivotally connected to bot of the arms 31 an 33.

The bracket 28 comprises a base 38 held parallel to the wall 12 by inturned portions or spacers 39, secured to the wall by a pair 5 of outstanding ears 41 formed integrally with the spacers 39.

A segment gear 47 is formed on the outer periphery of the arm 31 and meshes with a pinion 48 pivotally mounted adjacent the uper end o the plate 38; the pinion 48 being riven b a hand crank 50 through a releasable spring clutch 51. The arm 31 is pivotally mounted through the center of the segmental gear 47 to the plate 38 through a suitable pin 44 which is herein shown as' being riveted at bothA ends, and having a spacer holdin the arm 31 spaced from the plate 38. The andle projects through the wall 12 as shown in Fig. 3 and into the interior of the car to permit a passenger to actuate it l to raise or lower the window.

As best shown in Fig. 5, the bracket 29 comprises a base which has a shoulder 56 containing a shaft 57, the shaft having a reduced portion 58 upon which the arm 33 is mounted, the arm 33 being retained on the shaft 58 b means of a cotter pin 58 or equivalent hol ing means. The arrangement of the reduced portion 58 of the shaft 57 is ysuch that the shoulder between the twor is formed in the same plane as the plate 38. Since the pivotal points 44 and 58 are on the same plane and the segment gear is formed on the outer edge of the arm 31, the arm 33 is bent u wardl as shown ati59 so that it lies in t e same orizontal plane with the end of the arm 31.

In order that the outer ends of the arms 31 and 33 be in the same plane, it is necessary to bend both arms 3l and 33 as shown at 60 and 61 respectively. It will be noted that, by properly positioning the bent out portions and 61, that the arms 31 and 33 are permitted tocross intermediate the ends of their movement so that the regulator moves from a position shown in Fig. 1 to a position shown in Fig. 2, without diiiculty.

' The link 35 is pivotally connected to both the arms 31 and 33 and forms a driving connection, transmitting the motion from the arm 31 to the arm 33. By properly positioning the link 35, the outer ends of the arm can be made to move up and down so that the are always in a horizontal plane.

'lyhe ends of the arms 31 and 33 are provided with buttons 64 which slide in horizontal grooves 66 in a mounting channel 68, iixedly attached to the channel 20 by weld-v ing or other suitable means, thev buttons 64 transmitting motion from the arms 31 and 33 through the channel 68 to the channel 20 and the window 17.

To install the regulator, the casing 15 is removed and the pane 17 pulled out of its casing and thence vertically past the u per limit oi its normal movement. The uttons di may then be inserted through suitable enlarged ports 69 and the pane 17 lowered and the casing l5 replaced.

In operation, the handle 50 may be turned, turning the pinion dt8 which actuates the segment gear i7 andV raises or lowers the arm 3l. Motion is' transmitted from the arm 31 through the link 35 to the arm 33 causing a corres ending motion of the arm 33. The motion rom the arms 31 and 33 is transmitted to the mounting channel 68 throu h the buttons 6e running in the groove 66 in the channel to raise or lower the window.

The clutch 51 is so arranged that it releases upon turning the handle in either direction, but grips its mounting member to 'restrain motion oit the y inion 4:8 upon a force being exerted throng the arm 31. y

Having thus described the invention, it will be seen that there has been provided a relatively simple window regulator adapted to various uses and thatit will be apparent that the regulator is of wider adaptability thanto automobiles and can be used to regulate any window or for other analogous uses.

It is not, therefore, desired to limit the invention to the precise form herein shown and described, but only by the scope of the appended claims.

What is claimed as new and desired to se'- cure by Letters Patent is:
